DOUBLETREE.

SPECIFICATION forming part of Letters Patent No. 548,382, dated October22, 1895. Application filed December 21, 1894:. Serial No. 532,558- (Nomodel.)

To all whom, it mayconcern:

Be it known that I, OWEN MCDERMOTT, a citizen of the United States,residing at San Jacinto, in the county of Riverside and State ofCalifornia, have invented a new and useful Improved Doubletree, of whichthe following is a specification.

My invention relates to that class of doubletrees which are designed tobring the singleto trees as near as practicable into the plane of thetongue to which the doubletree is attached.

The object of my invention is to provide a doubletree of this class ofvery great simplicr 5 ity and'possessing greater strength in comparisonwith its weight than doubletrees heretofore known and constituting anintegral doubletree which is complete in itself for attachment by clevisand pin to the tongue and by stay straps or chains to the axle.

The accompanying drawings illustrate my invention.

Figure 1 shows my improved doubletree in place upon the tongue, afragment of which 2 5 is shown and having the singletrees in place.

Portions of the stay-straps are also shown in place attached to thedoubletrea. Fig. 2 is a View of the doubletree detached without thesingletrees and stay-straps.

My invention consists in an integral doubletree, comprising two bars a,a, provided with singletree pin-holes b b and the clevis pinholes c 0',and united by the combined staystrap, clevis, and bar-connecting loops 6e,

5 arranged, respectively, near the ends of the doubletree behind thepoints, respectively, where the singletree pin-holes are located. ffindicate sin gletree-rests, which project outward beyond the loops atthe ends of the bars 4o to form bearings for the singletrees B B.

The doubletree A can be stamped from a single piece of flat metal andthen the connecting portions e 6 can be bent to bring the two bars a. aside by side, one above the 5 other-,as shown, with the singletree-spaceD between them, or the two bars may be made separately and the loops e eafterward attached thereto. The loops retain the doubletree-bars intheir proper position and do not interfere with the desired swingingmovement of the singletrees and serve for attaching stay-straps, asshown in Fig. 1.

The projecting singletree-bearings ff are in the same plane,respectively, with the doubletree-bars to which they attach, and they 55 form, together with the body of such bars on the other side of thesingletree pin-hole, a bearing for the middle of the singletree, andwhen the singletrees are in place and the singletree pivot-pins g g arein place the whole constitutes a complete doubletree and singletrees, inwhich there is no tendency upon the part of the singletrees to twist thedoubletree upon the tongue, and in which there is no superfluousmaterial or unnecessary weight. The doubletree can be attached to thetongue H by the ordinary clevis and pin I, and the stay-straps .I canthen be attached in the loops formed by the connecting portions 6 e',andthe appliance is then ready ya for use.

I do not broadly claim that it is new to mount singletrees between twoparallel bars; but I desire to claim the new specific simple structureshown, by which I accomplish the 7 objects specified.

, Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The improved integral double-tree set forth comprising incombination, the two metal bars arranged side by side with thesingle-tree space between them, and provided with the single-tree pinholes and the clevis pin holes; and the two combined bar-connecting andstay strap loops arranged respectively near the ends of the bars weldedthereto and connecting said bars together.

2. The improved integral double-tree set forth comprising in combinationthe two metal bars arranged side by side with the single-tree spacebetween them, and provided with the single-tree pin holes and the clevispin holes; the two combined bar-connecting and stay strap loopsarranged, respectively, 5 immediately behind the single-tree pin-holes,respectively, near the ends of the bars welded thereto and connectingsaid bars together,

bars substantially as and for the purpose set forth.

OWEN MODERMOTT.
